Glade: an audio library for Arduino

As part of the Talkoo workshop organized by iMAL and given by David Cuartielles, I developed a library for audio rendering and processing under the Arduino. The library is under development and a first version is available at:
http://code.google.com/p/glade/

The code uses an example from Michael Smith, available at
http://www.arduino.cc/playground/Code/PCMAudio

The library currently allows to write to a mono buffer and play the sound to 8000Hz. It includes a dataflow engine that can connect plugins (sources, effects, outputs).
